TUSA Underwater Vehicle Instruction & Riding Manual SAV-7 EVO2 Thank you for purchasing a TUSA underwater vehicle. The TUSA underwater vehicle is revolutionary new underwater vehicle equipped with functions and features that set it apart from previous models and other brands. Hands-free riding with the scooter saddle (PATENTED) Hands-free is an innovative riding style that allows an operator to steer the scooter with body movement; much like a seal. This inline body placement is more streamlined to eectively decrease fatigue, reduce air consumption, and extend your dive time. Go further, get there faster, and have a lot more fun along the way. The hands-free riding style increases your options while diving. You are no longer limited to the hands-on riding style required by other vehicles. The possibilities are endless. Variable speed control Quick and smooth speed control is now at your ngertip. Speed adjustments are made via an accelerator lever that changes the rotational speed of motor while vehicle is in use. Adjustments are very smooth, allowing user to ne tune speed. These enhancements are a signicant improvement on the TUSA vehicle series. This new design provides a far more advanced control system than is available on other underwater scooter. The TUSA underwater vehicle is not a heavy burden The hands-free riding style decreases fatigue, reduces air consumption, and extends your dive time. In the past some divers have become fatigued from the energy and eort required to hold and steer an underwater vehicle. In addition to being a potential source of fatigue, the traditional hands-on riding style requires the user to place themselves above the vehicle rather than inline. Improvement in transportation options The TUSA underwater vehicle improves your ability to transport items underwater. Your hands are free to carry what you need. Additionally, fold out wings on both sides of the saddle are available for towing the divers or attaching other items of equipment. The innovative TUSA underwater vehicle challenges divers to create and nd new techniques and methods of use. Go out and enjoy diving with this great new generation diving product.
